Description
ELOG allows an authenticated user to upload arbitrary HTML files. The HTML content is executed in the context of other users when they open the file. Because ELOG includes usernames and password hashes in certain HTTP requests, an attacker can obtain the target's credentials and replay them or crack the password hash offline. In ELOG 3.1.5-20251014 release, HTML files are rendered as plain text.

Executive Summary

CVE-2025-62618 is a stored cross-site scripting (XSS) vulnerability in the Electronic Logbook (ELOG) software. Authenticated users can upload arbitrary HTML files that are executed in the context of other users when they open these files. This allows attackers to steal usernames and password hashes included in certain HTTP requests, which can then be used to replay credentials or crack passwords offline. The vulnerability is fixed in ELOG version 3.1.5-20251014 by rendering uploaded HTML files as plain text, preventing script execution. [3]

Impact Analysis

This vulnerability can lead to credential theft by allowing attackers to execute malicious HTML/JavaScript in other users' browsers. Attackers can capture usernames and password hashes, potentially gaining unauthorized access to user accounts through replay attacks or offline password cracking. This compromises confidentiality, integrity, and availability of the system and user data. [3]

Detection Guidance

Detection can involve monitoring for uploaded HTML files in ELOG by authenticated users, as these files may contain malicious scripts. Additionally, inspecting HTTP requests for usernames and password hashes being transmitted can indicate exploitation attempts. Specific commands are not provided in the resources, but checking ELOG upload directories for HTML files and analyzing HTTP traffic for suspicious requests related to ELOG would be advisable. [3]

Mitigation Strategies

Immediate mitigation steps include upgrading ELOG to version 3.1.5-20251014 or later, where uploaded HTML files are rendered as plain text, preventing script execution. Additionally, it is advised not to run ELOG with self-registration or the execute facility enabled to reduce risk. [3]
